Not quite the same. <projectref> allowed the projects to be "running" in 
tandem and for dependencies to exist beteween the projects. e.g.

<projectref file="blah.xml" ref="blah"/>

<target name="test" depends="blah:init">
  <javac srcdir="${blah:src.dir}"/>
</target>

Syntax et al up for grabs but still very different from <ant>

<import> is closer to C #include than java import.

Yes. I am arguing for the current <import> with some limited changes.
